Find meshes recursive
More Python thing than Blender's one, but you can:
import bpy

def find_meshes_recursive( root, levels=10, meshes=None ):
    # Initialize the result once
    if meshes is None:
        meshes = []

    def recurse( parent, result, level, levels ):
        # Does nothing if level is reached
        if level &lt; levels:
            # Keeps meshes
            if parent.type == 'MESH':
                result.append(parent)
            # Look over children at next level
            for child in parent.children:
                recurse( child, result, level + 1, levels )
    
    recurse( root, meshes, 0, levels )
    return meshes

root = bpy.context.object

meshes = find_meshes_recursive(root, levels = 10)
print(meshes)

Note that you can also do it in non recursive way:
def find_meshes(root, levels=10, meshes=None):
    meshes = [] if meshes is None else meshes
    
    parents = [root]
    while levels &gt; 0 and parents:
        meshes.extend([obj for obj in parents if obj.type == 'MESH'])
        parents = [child for obj in parents for child in obj.children]
        levels -= 1
        
    return meshes
